Sports Mole rounds up all of the latest transfer news in La Liga on Thursday, December 17.
Thursday morning's La Liga transfer talk news roundup:
Manchester United to battle Juventus, Real Madrid for Sporting Lisbon youngster?
Manchester United have reportedly identified Sporting Lisbon youngster Nuno Mendes as a potential transfer target.
Despite being just 18 years of age, Mendes has already established himself in the Sporting first team, making a total of 10 starts this season.
However, the emergence of the left-sided player has inevitably led to interest from elsewhere, including from Real Madrid and Juventus.
According to O Jogo, United are also weighing up a big-money approach for the teenager in 2021.
The Premier League giants have a history of doing business with their Portuguese counterparts, having previously signed Cristiano Ronaldo, Nani and Bruno Fernandes.
After recently penning a five-year contract, Mendes is valued in the region of £40m.
Manchester United 'in hunt for Bayern Munich's David Alaba'
Manchester United are reportedly in the race to sign Bayern Munich defender David Alaba.
The Red Devils are understood to be in the market for a new centre-back in future windows, with Alaba just as capable playing in the heart of defence as he is on the left-hand side.
The 28-year-old is entering the final six months of his contract with the Bavarian giants, and the club have supposedly withdrawn their latest offer of a new deal for the versatile defender.
According to SportBild, United are eyeing a move for the Austria international, who supposedly dreamed of a move to Old Trafford during his days as a youth player.
However, Alaba is believed to be a man in demand, with the report stating that Manchester City, Paris Saint-Germain, Chelsea, Barcelona and Real Madrid are all in the hunt for the defender's signature.
Alaba has been a key player for Hansi Flick's side this term with 16 appearances in all competitions, scoring one goal and setting up another.
